IMPROVEMENT IN KNIFE-CLEANERS.

Specification forming part of Letters Patent No. 126,172, dated April 30, 1872.

-section online a l) of Fig. l. Fig. 3 is a section on line c d of Fig. 1.

Similar letters of reference indicate like parts in all the figures.

A represents a box for holding the rolls. The box may-be made of wood or other suitable material. B is the cork-roll, and C the brush-roll. These rolls are geared together from the shaft D. On the shaft D is fastened a circular plate, E, which is also covered with cork, and has a corresponding plate covered with brushes, which I denominate the brushplate F, placed opposite the cork-plate, and kept in contact with it by the spring Gr.

The shaft D is revolved by the crank H, and transmits motion, through the gears I and K,

to the brush and cork rolls, so that both are operated and may be used together. The pressure between the rolls B and C is made adjustable by the springs L, the brush-roll being set in adjustable boxes having a vertical movement for that purpose. The polishingpowder usedV is introduced through the hopper M, and the surplus powder falls into the drawer N, from which it may be taken and used over again, if desired.

The knife to be polished is introduced between the rolls B and C through the opening O in the end of the box, and to the plates E and F through the opening Pin the top of the box.

The plates E and F are especially designed for cleaning forks, for which they are better adapted than the rolls.

I claim as my invention- In an apparatus for cleaning knives, the combination of the plates E F and rolls B C, operating together by the means and in the manner for the purpose set forth.
